int8_t is limiting the pins that can be used with the library.

This is not an issue per se.

I recently picked up an STM board and tried to convert one of my Adafruit EPD projects for that. The issue is the pins I am using can not be fit in an int8_t. For example, I am using a pin PB13, and according to STMduino that equals 205, which turns out to be -51 in an int8_t.

I cannot change the pins, because the board is already manufactured. I guess for now I will have a local copy of the library where all the pins are changed to int16_t.

Let me know if there is a better way to handle this.

Thanks in advance.

ok want to try a PR to change the pins to int16_t?
